T0 all whom 1113 mag; concem:

Be i1; known that I, WILLIAM H. BAKER, a citizen of t l1@ Unitecl Statesresidi ng at Olympia, in the county of Thurston und State 0f Washington,lmve invented a new and useiul Car-St-ake, of wl1ich the following is a.specilication.

-Tl1is invention relates 130 load-retaining means for vehicles, andespecially 150 means whereby pivoted sicle stakes upon platform andloggi1'xg ca1s may be held in vertical position against the pressu1e ofa loacl 01 may be easily released from a position 0f safety.

T110 purpose 0f this invention is 130 provide 21 device of the chamcterdescribed tl1at may be easily con structed af1d applied to any car andthat Will be durable and eflective in operation.

In 1;he accompanying clmwing of tl1is device: Figure 1 is a frontelevation showing the device in loacl-retaining osition attached 130 thesil1 of 21 car; and Fig. 2 is' an end elevation 017 the same showing thedevice in loadreleasing position. Fig. 3 is 21 top plan view 01 aportion of the lock bar ancl pin and sl1owing the adjacent side post andbracke1; in section.

Referring 130 the drawing, the side stakes 1 are pivotally attached a1;their lower encls 10 the sides 2 of 1;he car by mezu1s of 1;he bmckets 3and tlieir free ends are held in vertical position by tl1e lock bar 4which is slidably m0un1;ed agains1; 1;l1e outside 017 the car, parallel10 2mnd near 1;he upper edge thereof, in the brackets 55 which arerigidly secured 130 the sides of the car and ad jacen1; to the sa.idstakos. The lock bar carries the locking ins 66 rigidly secured tl1eretoby means 0f lugs ancl adaptecl t0 engage in'1'ecesses in the outer ends0f 1;]ie said brackets supportixlg said lock bar, t0 inclose the sidesta.kes when in thei1 vertical positions and 1:0 retain them agains1;tl1e pressure 0f a load. lhe lower eclge of said lock bar is too1;hedalong its cenbral Portion 130 form a rack 7; a gear wheel 8, meshingWith sai l rack, is mounted upon a sl1aft 9 passing through the sides oftl1e car and journaled therein; the ends of said shaft are adaptecl 110receive a removable cmnk 0r wrench whereby 1;l1e shaf1; may be turned,ro1;ating the gear and moving the lock bar longitudinally 01 the cm andcarrying t]1e locking pins into 01 out of engagement Wi1;h the recessesin the lock bar supporting brackets. The 1ock bar is positively retainedina position adapted to 10ck the side bars against the pressure 0f aload by means 0f 21 pin 10 removably placed in a hole in the baradjacent 21 bracket 11 through which tl1e bar passes and Which issecured to Ehe end 0f tl1e car.

In order 10 insure safety, the lock bar is operated fronri 13110 side ofthe c2nr opposite to tha1; 130 which it is attachecl When i1' is desiredt0 relegmse the side stakes from 21 load, but in locking tl1e stakeswhen 12110 caris unloaded 1;he bar may be more conveniently 0pera.tedfron1 1l1e san1e sicle to whicl1 it is atti1ched. I1; is 0bvious 1;hatt11e construction shown in the clmwing upon one side of tl1e cm only maybe applied t0 bo1;h 'sides if so desired. v

Having tl1us described tl1e invention, what is claimed 21.nd desired tobe secured by Letters Patent is:

1. In a loaclre1:aining means 101' v0hicles, the combination with aload-bearing structure, cf a side post pivotally 'securecl thereto, arecessed bracket secured to said stracture adjacent the post, 21 barslidably mounted in 1:he bracket transversely 0f said side p0st, alocking pin rigidly secu1'ed t0 the bar opposite said bracket, means foroperating said locking bar t0 cause the locking pin t0 engage 01'disengage with snid bl'acket, and n1eans for locking the bar when thepin is in engagernent With the bracket.

2. In loadretaining means f01' Vel1icles, the combination With aload-beal'ing structure, 01 a side post pivotally counected thereto, arecessed bracknt secured to said structure adjacent the post, a rack barslidably mounted in said bracket transversely of said post, a. lockingpin rigidly secured t0 said bar 0pposite the bracket, a gear wheel engaging said rack, and means fox rotating said gear.

3. In load-rotaining means f01' vehicles, tlle combination with aload-bearing structure, 0f a side post pivotally C011- nected theleto, arecessed b1'ack0t' secured 1:0 said structure adjacent 150 the post, arack bar slidably mountecl in said bl'ack0t trunsversely of the post, alocking pin rigidly secu1ed to the bar opposite 1:11e blacket, a gearwheel engaging said rack, and a shaft carrying said gear wheel andjournaled in und extending beyond the sides of said structure and havingends adapt'ed to receive a crank 01' wrench.

4. 'In a I0ad-retaining means.for vehicles, the combinati0n With aloadbearing structure, of a side post pivotally attached tlleleto, atransverse shaft journaled in said struc ture und extending beyoud tl1esides thereof, a gear mounted upon said sha1t, a movable 1'ack opersltedby the gear, and means opemted by said rack to lock 01' unlock the sidepost in a vertical position.

In testimony that I claim 12118 foregoing as my own, I have hereto z1tlixed my signatnre in the presence 0f 1;W0 witnesses.
